Stress is a normal part of everyday life, but it can worsen when a disaster happens in your area. Increased stress can negatively affect preexisting health conditions. Learn to manage daily stress before a disaster occurs to reduce its impact on your health.

It doesn't matter if you've failed with your habit efforts in the past. It doesn't mean you're lazy or weak-willed. It means you didn't have the right tools for making a lasting habit change.
What you need is a strategy for identifying your worst habits and learning how to overcome them. That solution is a book called: "Bad Habits No More: 25 Steps to Break ANY Bad Habit."
